Continuity mistake: When Jackie and the five men are fighting in the streets and Jackie's mother throws him two bottles, he breaks them on each other and he starts drinking. The first shot the bottles are broken when he is drinking. In the next shot when it changes from the head gangster and back to Jackie, the bottles aren't even broken. They are new bottles, with the lids removed. How can bottles repair themselves?

During the last fight between Jackie Chan and that well-dressed man, after the man gets his vest torn off by Chan, there passes a fight sequence with no audio whatsoever; you would expect to hear grunts and groans and hits, but some seconds pass with no audio.
